IMPROVEMENT IN HANGING-LAMPS.

- Specification forming part of Letters Patent No. 147,170, datedFctruary 3, 1874; application filed November 20, 1873.

To all whom it may concern Be it known that I, JOSEPH REINHOLD, of thecity, county, and State of New York, have invented a new and usefulImprovement in Hanging-Lamps; and I do hereby declare the following tobe a full and exact description of the same, reference being had to theaccompanying drawings, forming part of this specitication, in which-Figure 1 is a side elevation of my invention.

Similar letters of reference in the accompanying drawings denote thesame parts.

My invention relates mainly to verticallyadjusta-ble hanging-lamps andit has for its object to provide for public use a device for supportingand adjusting a hanging-lamp and its shade, which shall be cheap andsimple in construction, neat in appearance, and convenient in operation.To these ends the invention consists in the construction ofhanging-lamps, as hereinafter more fully set forth.

In the drawings, A represents the lampholder, consisting of a ring, B,provided with two rods, O, extending upward at each side, said rodsbeing curved inward for about half their length, and from thenceextending upward vertically parallel with each other. D

' represents a metallic smoke-bell, of sufficient weight tocounterbalance the holder A and lamp A. The smoke-bell is connected bychains E E with the ends of the rods 0 of the lamp-holder, the chainspassing upward through and over a cross-piece, F, suitably suspendedfrom the ceiling of a room, and from thence downward through orifices inthe edges of the bell, and hold the latter in place over the center ofthe lamp. The cross-pieee F is provided at its ends with groovedstationary segments G, over which the chains pass. H represents a ringhaving a beveled or curved periphery, adapted to support the shade F,and provided on its interior with sockets h h, located on oppositesides. These sockets inclose the parallel portions of the rods 0 of thelamp-holder, and slide thereon, so as to raise or lowerthe ring andshade.

It will be seen that the lamp is raised by lowering the smoke-bell, andVice versa, the weight of the bell counterbalancing that of the lamp.The latter, however, is liable to vary slightly in weight in proportionto the quantity of oil it contains. This variation is compensated for bythe friction of the chains E on the stationary segments G, and to someextent in passing through the orifices in the smoke-bell; hence the lampand bell will always remain in the relative positions in which they areleft. In case an unusually heavy shade should be employed, ornamentalmetallic tassels or pendants may be attached to the bell to increase itsweight. The chains E hold the bell directly over the lamp, so that itcannot become displaced. It is therefore as efficient as a glass orporcelain bell, such as is in common use, and is obviously moreeconomical, constituting as it does a combined weight and smoke-bell,and not being liable to break. The shade-supporting ring H, be ingbeveled or curved outward and downward from its upper edge, is adaptedto hold shades of difl'erent sizes, and should be made of white metal,or provided with an inner coating of such color as will reflect thelight. The

ring is made of small diameter at its upper edge, so that the light fromthe lamp is to a great extent intercepted and reflected back, while thesliding sockets h allow the shade to be adjusted vertically.

I am aware that a tube surrounding and sliding on a gas-tube, andprovided with tubular arms having two gas-burners at their extremitiessurrounded by shades, the sliding tube carrying the gas'jets beingbalanced or connterpoised by two weighted smoke-bells attached to cordsor chains, which pass over pulleys, and are connected with the slidingtube, have heretofore been employed; and I therefore lay no claim tosuch invention, Which requires the employment of two gas-jets, two

tionary grooved segments Gr G, in combination with the chains E E,lampholder A, and smoke-bell D, substantially as described.

2. The smoke-bell D, provided with perforations near its lower edge, incombination with the chains E E, supporting cross-piece F, andlamp-holder A, substantially as described.
